Reviews From A Fellow Cyclist

Love This FX Sport 4 Bike!

Finally found a bike that meets my needs!!! I wanted a lightweight bike that has the performance of a road bike, but with the control and comfort of flat handlebars. Bought the bike in late April, and so far have logged 115 miles on it, mostly on the rural, hilly roads of southwestern Wisconsin. I do group road rides and this bike enables me to pedal up the hills with ease, thanks to the numerous "granny" gears. I am 5'4" so I got the Small frame. Fits me well and it's a comfortable ride. Thank you, Trek, for making a great bike!

Features

Customize your bike with fenders, racks, bottle cages, and more to make it your own.

A 1x drivetrain means more versatility, simpler shifting and less things to go wrong. You still have a wide range of gears, but with lighter and more intuitive shifting. Everything you need and nothing more.

The all-new FX Sport has slightly less reach and slightly more stack than previous models for a more comfortable yet active and fast riding position.

Ultra high performance, within reach. The areal weight range and modulus mix of 400 Series OCLV provides an exhilarating sense of acceleration and confident handling.

Shimano GRX was designed from the ground up for gravel adventure. With its gravel-specific ergonomics, optimized gearing options, rugged reliability, and quiet, stable drivetrain, GRX sets itself apart from the rest of the component world.
